Description:
iDEFENSE has reported a vulnerability in HP-UX, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the debug logging routine of ftpd. This can be exploited to cause a stack-based buffer overflow by sending a specially crafted, overly long command request.

Successful exploitation may allow execution of arbitrary code, but requires that the FTP daemon is configured to log debug information (not default setting).

Solution:
Apply patches.
